Bored Puppy, Big Problem

As the title says, I have a puppy, a six month old Border Collie. She was being kept in the downstairs powder room, and managed to chew/scrape a hole in the exterior wall, pulling out fiberglass insulation and through the sheathing until I can see the vinyl siding through the hole. All in just a couple of hours. The hole itself is about 4" in diameter. My questions are:

How do I repair the vapor barrier?

What is the best way to re-insulate?

I think I can patch the drywall, but the rest of it is what concerns me. I am hoping to keep this repair as minimal as possible, dollar wise, time wise and effort wise, as I am tight on time and money and limited on tools and skills.

You first need a kennel to keep the pouch in, you will have to open the wall further, neatly cut insulation and fit in new pieces, redrywall, eat pouch, don't over cook it makes them tough

She slept in a cage last night, and for the foreseeable future. I've eaten a lot of things in my time, from alligator to camel, but I think I will pass here. Besides, she's a scrawny thing. Not much of a meal.

The sheathing is yellow inside, with a metallic foil exterior on each side. The yellow appears to be styrofoam with what feels like some fibers in it when I crumble it, if that makes sense. It is about fifteen years old, if that helps.

My camera cord is at work in my computer bag and not with my camera where it belongs. I will try to get some on my wife's phone and post them.

In addition to what Oh Mike said, teaching the dog to sleep in the kennel is a good thing. A lot of people do that from the time they bring them home. The kennel becomes 'their' special home, a place of refuge. When dogs start really chewing stuff like yours did, or digging holes in the back yard, it usually means they need exercise. Especially a breed like a border collie. Get the dog out and let her herd up the neighborhood kids or chase tennis balls till you're tired of throwing them. They need a workout, plus it's a lot of fun.

We also have a Australian Shepherd and a Jack Russell. We are strong believers in cage training. We were keeping the Aussie in the cage while the Border Collie was recovering from surgery, and they seemed to be dealing well with the situation, until I came home on Friday and found the mess. We live on an acre in the country and try to get them out as often as possible to run. The biggest problem is the obsessiveness of the Jack Russell and the Border Collie trying to "herd" her.

Well, I got it done. I have a nearly full size sheet of styrofoam sheathing and most of a 2x2 piece of drywall left, but those are the breaks. Where there were doubts, I taped the daylights out of it with foil tape, so hopefully I will have sufficient vapor barrier. It is in a relatively protected spot in relation to the exterior, which I hope will help. Now to just wait for the compound to dry, sand it and get it good and smooth and see if we have any paint left to match that is still liquid.
